Summary

This study tested a once-nightly extended-release form of sodium oxybate (FT218) in 157 adults with idiopathic hypersomnia, a condition causing excessive daytime sleepiness despite adequate sleep. Participants were already on stable doses of stimulants or other alerting agents. The trial measured changes in sleepiness and symptom severity over about 18 weeks. The goal was to see if FT218 can safely improve wakefulness and daily function.
